Problem opening excel spread*** using oledb

I am writing a web application as a administrative front end to a document
management system. One of the functions that I am developing is the ability
to import new users into the system via an Excel spread***. The specific
error code I am getting (if you want to call it specific) is 0x80004005 and
the message is 'unspecified error'.

My connection string is

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
HttpContext.Current.Server.MapPath(".//" + csv_store_read) + ";Extended
Properties=Exel 11.0;HDR=Yes"

Where HttpContext.Current.Server.MapPath(".//" + csv_store_read) is the
physical path to the file. The spread*** resides in a local folder on the
users machine and then when the import the file will be copied to the web
server. I've ensured that the folder on the server has the internet account
user configured for full access. I also read a couple of threads that said
to set up the Windows system directory to have the internet user account
assigned to it as well.

I also have impersonate set to true in the web.config file

Nothing is working I keep getting this error.

Any help/suggestions will be GREATLY appriciated.

Thanks,
Bill Youngman
